MTAR Technologies is a precision engineering company that makes the parts and assemblies inside nuclear reactors, space rockets, fighter jets, and clean-energy power units - the kind of components where a failure is not an option. Founded in 1969 by three engineers who wanted to build advanced technology inside India after trade embargoes cut off supply, it has spent over five decades moving from import substitution to exporting 82% of what it makes. The recurring approach is to lock onto a single large customer in a high-barrier sector - ISRO in space, NPCIL in nuclear, Bloom Energy in fuel cells - qualify over years as a trusted supplier, and then expand wallet share by moving from components to assemblies and sub-systems. # Business segments Four engines at different stages - a clean-energy export powerhouse that now dominates revenue, a nuclear business tied to India's reactor build-out, a space-and-defence franchise built on decades of ISRO and DRDO relationships, and a precision-components division that supplies the other three while chasing import-substitution orders of its own. ## 1. Clean energy - fuel cells, hydrogen and hydel: the export engine that transformed the company **A nine-year partnership with Bloom Energy turned MTAR into the sole Indian supplier of hot boxes and electrolyser power units for stationary fuel cells, and that relationship now pulls in adjacent orders for data-centre and battery-storage assemblies.** - **One customer, many boxes** - MTAR manufactures power units, sheet-metal assemblies, enclosures and cable harnesses for Bloom Energy's solid oxide fuel cell (SOFC) units, which generate power from methane with 66% less carbon than thermal plants, and power units for solid oxide electrolysers that split steam into green hydrogen. It was the only supplier to Bloom from India as of FY22 and has since moved into assembly work to increase its share of the customer's spending. - **Built ahead of demand** - the company commissions clean-energy capacity in advance for its customers, and a fresh expansion has already come online, so it can scale with Bloom's growth rather than chasing it. - **Raw materials passed through** - in the Clean Energy - Fuel Cells sector, a majority of raw materials are bought from customer-directed sources under annual price contracts, and any subsequent price increase is passed straight through to the customer, insulating MTAR from commodity swings. - **Hydel structures add heft** - for hydropower and wind customers including Andritz Hydro, GE Power and Voith, MTAR fabricates draft tubes, spiral casings, and rotor and stator assemblies, giving the segment a second, non-fuel-cell revenue stream. - **Data centres are the new adjacency** - the company has won first-article export orders worth Rs. 35 crores from SLB for AI data-centre infrastructure assemblies, with a long-term contract in place and a potential to reach Rs. 400-500 crores over the next couple of years. ## 2. Civil nuclear power: a 35-year moat inside India's reactor programme **MTAR supplies roughly a fifth of the precision equipment inside every Indian PHWR nuclear reactor, and with ten new reactors approved and refurbishment work ongoing, the order book sits above Rs. 650 crores.** - **Fourteen products per reactor** - the company makes fuelling machine heads (600-component assemblies that load and unload fuel bundles), bridge and column assemblies, coolant channel assemblies, drive mechanisms, grid plates and sealing doors, translating to an addressable market of Rs. 7-8 billion per 700 MWe plant. - **The customer is the gatekeeper** - NPCIL controls every operational, under-construction and planned reactor in India and does not allow private participation; MTAR is a pre-qualified vendor with a 16-year relationship, and its board includes a former NPCIL technical director. - **Only two or three bidders show up** - stringent qualification criteria mean most nuclear tenders attract minimal competition, giving incumbents like MTAR an edge that new entrants cannot easily replicate. - **Lumpy by nature** - nuclear orders are project-based and revenue recognition is uneven, which is why the segment contributed only 3% of FY26 revenue even though the order book stood at 26.3% of the total. ## 3. Aerospace and defence: the space-to-fighter-jet franchise **MTAR has been machining engines for ISRO's rockets since 1983 and structures for DRDO's missiles for over three decades, and it is now converting those credentials into long-term agreements with Israeli and European aerospace primes.** - **Engines that lift satellites** - the company makes liquid-propulsion engines (the Vikas engine for PSLV), cryogenic engine sub-systems including turbo pumps and injector heads, and India's first semi-cryo engine, which uses kerosene and liquid oxygen to raise GSLV payload capacity from 4 to 6 tons. - **From components to a launch vehicle of its own** - under an MoU with IN-SPACe, MTAR is developing a two-stage small-satellite launcher called Garuda 1 with 100-ton and 10-ton all-liquid engines designed in-house. - **Actuators and airframes for defence** - the company produces 5-ton and 10-ton actuators for the LCA Tejas Mark IA, magnesium gearboxes for helicopters, base shrouds for Agni missiles, and structural test boxes for the AMCA stealth-fighter programme. - **Global primes are signing on** - a 15-year agreement with Israel Aerospace Industries carries a business opportunity of $90-120 million, with first articles due by September 2026 and volume production starting the following month; long-term agreements are also in place with Thales and under discussion with GKN Aerospace. - **A defence licence unlocks the next tier** - a Defence Industrial License obtained in August 2023 allows MTAR to produce electronic subsystems, C4I systems and air-independent propulsion for submarines, enabling it to partner with foreign MNCs under India's 'Buy (Indian)' and 'Make' procurement categories. ## 4. Products: precision components that feed the other engines **Ball screws, roller screws and electro-mechanical actuators - all import substitutes - are made in this division and sold into the same nuclear, space and defence programmes the company already serves, with revenue expected to cross Rs. 200 crores in FY27.** - **Import substitution is the pitch** - ball screws and water-lubricated bearings replace imported parts in nuclear-reactor actuators, space-launch vehicles and missiles, and the company won a national award for import substitution in mission-critical systems. - **First to make roller screws in India** - roller screws were previously imported entirely from Sweden; MTAR has qualified its own and delivered first articles to DRDO, making it the first Indian manufacturer. - **Actuators open a new product line** - electro-mechanical actuators have drawn orders of roughly Rs. 7.5 crores with larger orders expected, and they can be used in self-defence missiles as well as space and defence applications. # Manufacturing and technology capabilities **Nine fungible factories in Hyderabad, over 400 machines and in-house special-process shops give MTAR the flexibility to shift capacity across nuclear, space, defence and clean-energy work without dedicated lines.** - **No factory is locked to one sector** - Unit 1 handles nuclear assemblies and Agni-missile base shrouds; Unit 2 builds cryogenic and semi-cryo engines; Unit 3 runs high-volume nuclear parts and ball screws; the export-oriented unit makes fuel-cell hot boxes and MNC aerospace components, and all can be rebalanced as orders shift. - **Special processes stay in-house** - surface treatment (nitriding, anodizing, hard chrome and nickel plating, passivation), heat treatment, electron-beam and orbital welding, vacuum brazing, and clean-room assembly (10,000-class rooms with 100-class laminar tables) are all done internally, so quality and lead times are not outsourced. - **Machines built, not just bought** - the company has designed and built sophisticated special-purpose machines like the Gantry SPM in-house instead of importing them, cutting capital costs while creating tools tailored to its own workflows. - **Exotic alloys, managed supply** - key raw materials include Inconel, 17-4 PH and 13-8 MO, a significant portion imported from authorised suppliers in the US, Brazil and Europe, while over 40% of raw materials come from local vendors cultivated over five decades. # Group structure and partners **A listed holding company with two wholly-owned subsidiaries - both now being merged back in - and board-level relationships that open doors in nuclear and defence procurement.** - **Subsidiaries served a purpose, now being absorbed** - Gee Pee Aerospace was acquired in 2022 to add capacity and tap MSME benefits including a 1.5x offset credit multiplier for foreign OEMs; Magnatar Aero was incorporated in 2019 for defence offset partnerships but had zero turnover as of March 2025; the board approved merging both into the parent in May 2025. - **Board expertise matches the order book** - the board includes a former technical director of NPCIL and a former DRDO scientist, giving the company domain fluency and relationship continuity in its two largest government-facing segments. - **IN-SPACe partnership for the launch vehicle** - the MoU with IN-SPACe for the Garuda 1 small-satellite launcher is structured under a Joint Project Implementation Plan where MTAR pays ISRO for work packages, giving it access to the national space agency's test and launch infrastructure.
